NUT-LOCK- Specification of Letters Patent;

Patented Nov. 6, 1906.

Application filed December 9, 1905. Serial No. 291,120.

To all whom it may concern:

Be it known that I, WILLIAM SHEAD MA- SON, a citizen of .the United States, and a resident of La Salle, in the county of Lasalle and State of Illinois, have invented new and useful Improvements in Nut-Locks, of which the following is a full, clear, and exact description. 1

Thisinvention relates to nut-locks; and it consists, substantially, in the details of con struction and combinations of parts hereinafter more particularly described, and pointed out in the claims.

One of the principal objects of the invention is to provide a nut-lock of an embodiment to overcome numerous disadvantages upon a bolt.

and objections encountered in the use of many other structures of the kind hitherto devised.

A further object is to provide a structure of the character referred to which is simple in its embodiment and comparatively inexpensive to manufacture besides being effective and reliable for its purposes and possessing the capacity for long and continued service.

The above and additional objects are attained by means substantially such as are illustrated in the accompanying drawings, in which I 1.

Figure 1 is a side view representing my improvements as employed for looking a nut Fig. 2 is a transverse sectional view on the line 2 2 of Fig. 1. Fig. 3 is a similar view to Fig. 1, taken from the opposite side to that shown in Fig. 1. Fig. 4 is a view of the blank employed in the construction'of the adjustable case of myimproved nut-lock. Fig. 5 is a sectional View representing a slightly-modified form of my improvements. Fig. 6 is a front view thereof, and Fig. 7 is a view of the blank employed in the construction of the adjustable case shown in Figs. 5 and 6.

Before proceeding with a more detailed description it may be stated that in the forms of my improvements herein shown I employ a bolt or the like provided with a hole extending therethrough transversely a suitable distance from the free end of the threaded portion thereof, a nut being employed on'the bolt and a locking-pin extending through the hole in the bolt, as will be explained. I also employ a specially-constructed member,

preferably termed by me a case, having slidable relation with the nut and cooperating with the locking-pin in such manner as that when the parts are operatively associated or combined with each other neither ;part can turn independently of the others. 2 My improvements are applicable to either square, hexagonal, or octagonal nuts and are effective in locking the nut in the desired po- I sition thereon on the bolt without requiring I any extra turning of the nut in either direction. My improvements are also applicable 3 for their intended purposes irrespective of the particular numbers of turns required to be made of the nut upon the bolt in order to bring the transverse holes in the bolt and the case Reference being had to the drawings by the designating characters thereon and with reference .to Figs. 1 to 4, inclusive, 1 repre+ sents an ordinary bolt, threaded at 2 for a suitable distance from one end and ,provided at the other end thereof with a head 3, said bolt being provided with a hole 4, extending substantially transversely therethrough and being located a suitable distance from that end of the bolt from which the same is threaded, said hole extending through the longitudinal axis of the bolt, as shown in Fig. 2. Screwing upon the threaded portion 2 of the bolt is a nut 5, herein shown as a square. nut, although it will be understood that either a hexagonal or octagonal nut may be employed, so far as my improvements are C0111 corned.

in proper registry to receive the lockingpin.

Fitting upon the nut 5 at opposite sides I thereof is what I term a slidable case 6, the same being constructed or madeup from a blank 7, such as is indicated in Fig. 4:, said blank being bent on the broken lines 8, 9., 10, I

11, and 12, so as to produce the case, the ends of the blank being preferably reduced in thickness, as shown in Fig. 2, and overlap.- ping each other and secured in any suitable way, as by means of rivets 13 it being noted that the substantially central portion 7 of the blank forms in the completed case the outwardly-curved side 14 thereof, while the end portions 15 and 16 of the blank form in the completed case the opposite and reverselynotches 23, alternating with those of each Formed in the fiat side 19 of the case 6 of my improved nut-lock is a series of holes 25, preferably circular in form and provided at the edges thereof with inwardly-extending projections 26 for the purpose of effecting binding engagement with a cotter-pin 27, for instance, which is inserted through the desired one of the openings after the nut has been properly turned upon the bolt, a part of said cotter-pin 27 being thereby caused to extend through one or another of the notches 23 in the opposite edges or sides of the slot or elongated opening 22 in the flat side 18 of the case.

It will be understood that the cotter-pin 27 is preferably provided with a head at one end, and said pin is of a size to fit any one of the openings 25 in the case 6 and the hole in the bolt and any one of the arcs or notches 23 in the slot 22 in the case, the pin bending the centrally-disposed point or projection 24 in the slot 22 outwardly, thus causing a binding engagement between the pin and said notch 23. It will also be understood that the notches 23 are of the proper relative size to receive and bind the pin 27 whether the pin passes through the slot 22 at right angles to the case or at some other angle thereto. It will be further understood that the head of the pin after being inserted rests against one side of the case and that the other end of the pin is bent downward toward or against the opposite side of the case, thus effecting anchoring engagement between the opposite parallel sides of the case.

It will be understood that the openings 25 in the case 6 are of the proper relative size to receive and bind the cotter-pin 27 whether the pin passes through an opening 25 at right angles to the case or at some other angle thereto and that the projections 26 in the perforations 25 in the case are bent at right angles or at some other angle in inserting the eotterpin, said projections pressing against said pin and, together with the binding engagement of the pin at either end with the case, insuring a tight fit.

In the practical application of this nutlock the double adjustment feature, due to the reversible feature of thecase 6, may also be accomplished by constructing the cases in pairs, the one supplementing the other, the perforations in either being placed at points answering to the relative positions of all perforations in the reversible case, thus effecting economy of material and space. Likewise pairs of cases may be used in the form of construction shown in Fig. 7, perforations being used instead of a slot.

By means of the embodiment of my improvements thus described the case 6 may be so moved upon the nut as to be brought into a position thereupon corresponding to any particular turn of the nut upon the bolt, as will be apparent, and the position of the cotter-pin 27 relatively to the bolt and nut will be either at right angles to the flat sides of the ease or at some inclination with respect thereto, according to the particular adjustment of the case upon the nut. When the parts are associated or combined together for use in the manner explained, neither the bolt nor the case can turn independently in either direction, and consequently it will be seen that my improved nut-lock is thoroughly effective and reliable in the carrying out of its intended functions.

As shown in Figs. 5 to 7, inclusive, my improved case 6 is constructed from a blank 28, (indicated in Fig. 7,) said. blank being oblong in form and provided at a suitable distance from one end thereof with a lateral extension 30, in which is formed a slot or elongated opening, in the opposite sides or edges of which are formed or cut opposite series of curved notches 31, alternating with those of each series of which are points or projections 32, those on either side of the slot or opening being disposed before and substantially central of the notches opposite thereto, substantially as has already been explained with reference to the form of case shown in Figs. 1. to 4, inclusive. To form or make up my improved case 6 the blank 28 is bent upon the broken lines 33, 34, 35, and 36, the ends of the blank being reduced in thickness and. joined together in any suitable way, as by means of rivets 37, Fig. 6, it being here men tioned that the nut 38 shown in Figs. 5 and 6 is hexagonal instead of square, as shown in Fig. 2, although, if desired, a square nut can be employed with this form of my improvements. In applying the said case 6 after the nut 38 has been turned upon the threaded portion 2 of the bolt to the desired position the case 6" is moved in one direction or the other upon the nut to bring any one of the notches 31 into registry with the aforesaid hole in the bolt, and then a cotter-pin 39 is inserted through the said structure substantially in the manner already explained with reference to the first form of my improvements described, it being apparent that with either form of my improvements the ends of the cotter-pin are turned or bent to prevent the same from becoming loose or falling out of position.

In the use of either form of my improvements it will be seen that the case may be moved upon the nut in conformity with any particular alinement or adjustment of the openings and notches in opposite sides of the case with the registering hole in the bolt irrespective of the particular number of turns of the nut upon the bolt and without having to turn the nut to bring it into alinement, all adjustments necessary to be made being effected by moving the case in one direction or the other, as already explained.

It will be noted that the reversible features of the case. 6 have the effect of doubling the adjustment centers in the case, that the sides of the case are spaced apart sufficiently to insure a tight fit of the case on the two sides of the nut to which the case may be applied, and that the outwardly-curved sides of the case admit of the increase of the space be.- tween the parallel sides of the case to facilitate the sliding of the case over the nut, with the result that a tight fit is always secured.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. A nut-lock, comprising abolt having a hole extending transversely thereof, a nut on the bolt, a casing comprising substantially parallel sides for engaging opposite faces of the nut and arched ends connecting the sides whereby to permit the adjustment of the casing to the nut, and a pin traversing the parallel sides and the opening in the bolt.
